Please mark this project as obsolete

[marc-guenther]

As this project does not do anything useful, and you obviously have no intention of continuing it, could you please:

• mark this clearly in the README?
• maybe put a link to Unofficial GitHub Copilot integration with Eclipse, which works perfectly fine?

This project here shows up very prominently in Google results, and advertises itself as "This is an open source implementation of the Github Copilot AI Model based on reverse engineering of the VSCode and IDEA plugins", which is highly misleading.
